Penstemon Geoff Hamilton

Penstemon Geoff Hamilton has very bright flowers with 1 3 and 4 inch tubes and lobes of bright deep cerise. The interior of the tubes are marked with burgundy guidelines. An ideal candidate for adding to moss animal topiaries. The foliage is rich green and fairly wide and long. We grow this in a red section of the Four Seasons Garden where it has added long term interest to Vitis vinifera Purpurea and nearby Berberis Helmond Pillar. All of the garden hybrid Penstemons need full sun and well drained soil. We mulch the crowns with 1 and 4 to 10 crushed gravel which discourages crown rot by letting water drain off the crown quickly. When planting Penstemons we fertilize them only lightly and then never again. Over fertilizing Penstemons promotes the development of lush soft growth which leads to excessive die back in the winter.
